Weather Observation Station 6

Problem Statement : Query the list of CITY names starting with vowels (i.e., a, e, i, o, or u) from STATION. Your result cannot contain duplicates.

where LAT_N is the northern latitude and LONG_W is the western longitude.


Solution :

For this challenge, we must:

  1. Use a Distinct() function to get unique cities.

  2. Restrict the selected rows using the WHERE clause so that only records where CITY names start with vowels are returned.


Query :

SELECT Distinct CITY 

FROM STATION 

WHERE city like 'a%' or city like 'e%' or city like 'i%' or city like 'o%' or city like 'u%';



Output:
